The VSC-4KX-IQ is a high quality polyphase scaler for up/down/cross conversion between video formats up to 4K resolution. The VSC-4KX-IQ up converts SD/HD video signals to 4K resolution and down converts 4K inputs to SD or HD. In addition, the VSC-4KX-IQ can cross convert a 4K input to a 4K output with up/down scaling. Both 2-Sample Interleave and Square Division 4K formats are supported. Pixels at the boundaries between tiles are processed correctly such that no seams are ever visible. The scaler may be used in conjunction with the VPC-1 Video Processor and Deinterlacer IP core or with any other customer or third party IP. Support for any scale factor allows full screen display of any input as well as arbitrary resizing for PIP and multiviewer applications. In addition, the core includes a number of Verilog parameters that allow it to be tailored at build time to satisfy specific requirements. Flexibility and robust design combine to make the VSC-4KX-IQ ideal for both consumer electronic and broadcast applications.
The VSC-4KX-IQ is available with complete Verilog source code, Verilog test bench and bit-accurate C models as part of the license. Integration and programming guidelines are also included backed up by expert technical support.
A VSC-4KX-IQ reference design is available for standard development kits from Xilinx and Altera for demonstration and evaluation purposes. The design includes a built-in user interface with embedded OSD to simplify access to key features of the IP. In addition to simplifying the evaluation of the VSC-4KX-IQ IP core, the design also serves as a template for customer application development.
